Interesting Touch Screen Lag Research

Staff MemberPremium Supporter

If you are moving your finger at 1 meter per second on an average 100 millisecond touch screen, your object will eventually become about 10 centimeters behind. At Microsoft Research, they have been trying to decrease the latency associated with touch screens. Albert Ng and Paul Dietz of the Applied Sciences Group explain what it will mean for artists and regular users to remove rubber banding by bringing about a 1 millisecond touch screen response time. Current tablets are compared with possibly faster ones in the future.

In the future, these systems will help your fingers feel like you are moving a real physical object. The video does not take into account sensitivity detection and vectoring - common issues on modern tablets and slates that are slowly being improved. For example, pushing down harder can result in a thicker response with a pen draw.
